[Rd] Minor quibble with eigen and La.eigen (PR#3221)
Hi everyone, It's a very minor point, but could we ensure that eigen and La.eigen return a *matrix* for the "vectors" component of the list by including a "drop = FALSE", as specified in the help file, ie put list(values = z$values[ord], vectors = if (!only.values) z$vectors[, ord, drop = FALSE]) Thanks, Jonathan. --please do not edit the information below-- Version: platform = i686-pc-linux-gnu arch = i686 os = linux-gnu system = i686, linux-gnu status = major = 1 minor = 7.0 year = 2003 month = 04 day = 16 language = R Search Path: .GlobalEnv, Autoloads, package:base

We certainly can. (svd seems to do this already.) Could you (next time) supply a test example for the regression suite, though?
